two same colour compounds when mixed change colour?
Just curious about something if someone could shed some light on this?
I have made both pure cyclohexanone semicarbazone and furaldehyde semicarbazone that are a similar colour of white with differring crystals.
I ran a thermodynamic competitve reaction to form both and the resulting colour is a slightly off yellow colour. But the major product here is
furaldehyde semicarbazone.
When i ran the above competitve reaction again under kinetic control (major product is cyclohexanone semicarbazone) the colour is still similar to the
pure cyclohexanone semicarbazone (white).
What has caused this colour change on the thermodynamic product? Something to do with chromophores?

Sounds like polymerized ketone or aldehyde crap to me.
